It was very useful. When I asked the shop, it was expensive and time consuming, and I couldn't adjust the date and time well, so I did it with DIY. I used an air gun to spray it with the cleaning liquid, and finally washed it with hot water, and I was able to clean it with the air blown. All the dirt went into the bucket and I was able to clean it smartly without getting the surroundings dirty. Is it about 60% disassembly / assembly and 40% cleaning? It looks like you'll feel very comfortable in the coming summer. (Translated by machine.)
